Heading west from coastal Oregon we are able to make our initial seismic images beneath the seafloor continuously as we go. Where once our data would have been recorded on magnetic tapes only to be analyzed long after the expedition was over, thanks to the wonders of modern signal processing, we can now make images [...]

In the research expedition now underway, we will investigate the Juan de Fuca plate before it disappears under North America to understand why earthquakes happen where and when they do within the Cascadia subduction zone off the Pacific Northwest. Our ship, the R/V Marcus G. Langseth, is one of 25 research vessels available to U.S. scientists for oceanographic research.
